Any idea when duplication multiplexing will be available? When I look at my drives as a duplication is happening...it is shoe-shining. Write a little data....spin the tape...write a little data....spin the tape. The manufacturer of the drives says this is a BIG problem with Netbackup an duplication jobs. I have replaced 3 L5 drives in the past month. I can olny assume it is due to the duplication jobs. Thank god for waranties.
